Gender stereotypes and social perception of vocal confidence is mitigated by salience of socio-indexical cues to gender.

Introduction: Socio-indexical cues to gender and vocal affect often interact and sometimes lead listeners to make differential judgements of affective intent based on the gender of the speaker. Previous research suggests that rising intonation is a common cue that both women and men produce to communicate lack of confidence, but listeners are more sensitive to this cue when it is produced by women. Some speech perception theories assume that listeners will track conditional statistics of speech and language cues (e.g., frequency of the socio-indexical cues to gender and affect) in their listening and communication environments during speech perception. It is currently less clear if these conditional statistics will impact listener ratings when context varies (e.g., number of talkers). Methods: To test this, we presented listeners with vocal utterances from one female and one male-pitched voice (single talker condition) or many female/male-pitched voices (4 female voices; 4 female voices pitch-shifted to a male range) to examine how they impacted perceptions of talker confidence. Results: Results indicated that when one voice was evaluated, listeners defaulted to the gender stereotype that the female voice using rising intonation (a cue to lack of confidence) was less confident than the male-pitched voice (using the same cue). However, in the multi-talker condition, this effect went away and listeners equally rated the confidence of the female and male-pitched voices. Discussion: Findings support dual process theories of information processing, such that listeners may rely on heuristics when speech perception is devoid of context, but when there are no differentiating qualities across talkers (regardless of gender), listeners may be ideal adapters who focus on only the relevant cues.

How Does the Accuracy of Children's Number Representations Influence the Accuracy of Their Numerical Predictions?

Predictions begin with an extrapolation of the properties of their underlying representations to forecast a future state not presently in evidence. For numerical predictions, sets of numbers are summarized and the result forms the basis of and constrains numerical predictions. One open question is how the accuracy of underlying representations influences predictions, particularly numerical predictions. It is possible that inaccuracies in individual number representations are randomly distributed and averaged over during summarization (e.g., wisdom of crowds). It is also possible that inaccuracies are not random and lead to errors in predictions. We investigated this question by measuring the accuracy of individual number representations of 279 children ages 8-12 years, using a 0-1,000 number line, and numerical predictions, measured using a home run derby task. Consistent with prior research, our results from mixed random effects models evaluating percent absolute error (PAE; prediction error) demonstrated that third graders' representations of individual numbers were less accurate, characterized by overestimation errors, and were associated with overpredictions (i.e., predictions above the set mean). Older children had more accurate individual number representations and a slight tendency to underpredict (i.e., predictions below the set mean). The results suggest that large, systematic inaccuracies appear to skew predictions while small, random errors appear to be averaged over during summarization. These findings add to our understanding of summarization and its role in numerical predictions.

Gender stereotypes drive perceptual differences of vocal confidence.

One's ability to express confidence is critical to achieve one's goals in a social context-such as commanding respect from others, establishing higher social status, and persuading others. How individuals perceive confidence may be shaped by the socio-indexical cues produced by the speaker. In the current production/perception study, we asked four speakers (two cisgender women/men) to answer trivia questions under three speaking contexts: natural, overconfident, and underconfident (i.e., lack of confidence). An evaluation of the speakers' acoustics indicated that the speakers significantly varied their acoustic cues as a function of speaking context and that the women and men had significantly different acoustic cues. The speakers' answers to the trivia questions in the three contexts (natural, overconfident, underconfident) were then presented to listeners (N = 26) in a social judgment task using a computer mouse-tracking paradigm. Listeners were sensitive to the speakers' acoustic modulations of confidence and differentially interpreted these cues based on the perceived gender of the speaker, thereby impacting listeners' cognition and social decision making. We consider, then, how listeners' social judgments about confidence were impacted by gender stereotypes about women and men from social, heuristic-based processes.

Contextualized Knowledge Reduces Misconceived COVID-19 Health Decisions.

How do we resolve conflicting ideas about how to protect our health during a pandemic? Prior knowledge influences our decisions, potentially creating implicit cognitive conflict with new, correct information. COVID-19 provides a natural condition for investigating how an individual's health-specific knowledge (e.g., understanding mask efficacy) and their personal context (e.g., outbreak proximity) influence their protective health behavior endorsement, as information about the virus, its spread, and lethality has changed over time. Using a dual-process-model framework, we investigated the role cognitive conflict has on health decision-making. We used a computer mouse-tracking paradigm alongside geographical information systems (GIS) as a proxy for context. The results support a contextualized-deficit-model framework in which relevant knowledge and context-based factors help individuals override cognitive conflict to make more preventative health decisions. Findings from this study may provide evidence for a more effective way for experts to combat non-adherence due to conflicting health information.

Predictions of Miscommunication in Verbal Communication During Collaborative Joint Action.

Purpose The purpose of the current study was to examine the lexical and pragmatic factors that may contribute to turn-by-turn failures in communication (i.e., miscommunication) that arise regularly in interactive communication. Method Using a corpus from a collaborative dyadic building task, we investigated what differentiated successful from unsuccessful communication and potential factors associated with the choice to provide greater lexical information to a conversation partner. Results We found that more successful dyads' language tended to be associated with greater lexical density, lower ambiguity, and fewer questions. We also found participants were more lexically dense when accepting and integrating a partner's information (i.e., grounding) but were less lexically dense when responding to a question. Finally, an exploratory analysis suggested that dyads tended to spend more lexical effort when responding to an inquiry and used assent language accurately-that is, only when communication was successful. Conclusion Together, the results suggest that miscommunication both emerges and benefits from ambiguous and lexically dense utterances.

Cognitive Processing of Miscommunication in Interactive Listening: An Evaluation of Listener Indecision and Cognitive Effort.

Purpose The purpose of the current study was to evaluate the social and cognitive underpinnings of miscommunication during an interactive listening task. Method An eye and computer mouse-tracking visual-world paradigm was used to investigate how a listener's cognitive effort (local and global) and decision-making processes were affected by a speaker's use of ambiguity that led to a miscommunication. Results Experiments 1 and 2 found that an environmental cue that made a miscommunication more or less salient impacted listener language processing effort (eye-tracking). Experiment 2 also indicated that listeners may develop different processing heuristics dependent upon the speaker's use of ambiguity that led to a miscommunication, exerting a significant impact on cognition and decision making. We also found that perspective-taking effort and decision-making complexity metrics (computer mouse tracking) predict language processing effort, indicating that instances of miscommunication produced cognitive consequences of indecision, thinking, and cognitive pull. Conclusion Together, these results indicate that listeners behave both reciprocally and adaptively when miscommunications occur, but the way they respond is largely dependent upon the type of ambiguity and how often it is produced by the speaker.

Contrast Is in the Eye of the Beholder: Infelicitous Beat Gesture Increases Cognitive Load During Online Spoken Discourse Comprehension.

We investigated how two cues to contrast-beat gesture and contrastive pitch accenting-affect comprehenders' cognitive load during processing of spoken referring expressions. In two visual-world experiments, we orthogonally manipulated the presence of these cues and their felicity, or fit, with the local (sentence-level) referential context in critical referring expressions while comprehenders' task-evoked pupillary responses (TEPRs) were examined. In Experiment 1, beat gesture and contrastive accenting always matched the referential context of filler referring expressions and were therefore relatively felicitous on the global (experiment) level, whereas in Experiment 2, beat gesture and contrastive accenting never fit the referential context of filler referring expressions and were therefore infelicitous on the global level. The results revealed that both beat gesture and contrastive accenting increased comprehenders' cognitive load. For beat gesture, this increase in cognitive load was driven by both local and global infelicity. For contrastive accenting, this increase in cognitive load was unaffected when cues were globally felicitous but exacerbated when cues were globally infelicitous. Together, these results suggest that comprehenders' cognitive resources are taxed by processing infelicitous use of beat gesture and contrastive accenting to convey contrast on both the local and global levels.

Social Judgments of Digitally Manipulated Stuttered Speech: Cognitive Heuristics Drive Implicit and Explicit Bias.

Purpose People who stutter are susceptible to discrimination, stemming from negative stereotypes and social misattributions. There has been a recent push to evaluate the underlying explicit and implicit cognitive mechanisms associated with social judgments, moving away from only evaluating explicit social bias about people who stutter. The purpose of the current study was to evaluate how listeners change their implicit and explicit social (mis)attributions after hearing a people who stutter produce disfluent speech. Method The current project was an adaptation of the Byrd et al. (2017) study to evaluate listener implicit/explicit social judgments of stuttered speech across five categories (i.e., confidence, friendliness, intelligence, distractibility, and extroversion) before and after a stuttering self-disclosure. This was done by implementing a modified version of the Ferguson et al. (2019) computer mouse-tracking paradigm. Results Consistent with previous findings, participants made more explicit positive social judgments of confidence, friendliness, extroversion, and intelligence after a stuttering self-disclosure, but the distractedness category was resistant to change. Also consistent with previous findings, participants experienced a higher degree of cognitive competition (i.e., higher area under the curve) shortly after self-disclosure, which lessened over time. Conclusions Explicit and implicit biases exist, but self-disclosure significantly impacts the cognitive system of listeners. Specifically, self-disclosure may reduce explicit bias through experience and explicit belief updating, but when cognitive heuristics are strong, implicit bias may be slower to change.

Social Judgments of Digitally Manipulated Stuttered Speech: An Evaluation of Self-Disclosure on Cognition.

Purpose Persons who stutter (PWS) may be susceptible to discrimination because of negative judgments made by listeners. The current study sought to determine how the cognitive system's explicit (i.e., conscious) and implicit (i.e., nonconscious) biases about PWS are impacted by self-disclosure. Method A computer mouse-tracking paradigm was used to evaluate categorical social judgments about PWS. Computer mouse trajectories, which have been shown to reveal underlying cognitive pull or competition between opposing concepts, were used to measure implicit bias (i.e., nonconscious stereotypes). Participants were asked to explicitly categorize the speaker as either intelligent or unintelligent before and after listening to a speaker self-disclose. Mouse cursor trajectories during the explicit response categorization were used to evaluate implicit bias associated with the decision-making process. Results Results indicated that participants chose "intelligent" for a higher proportion of the trials in the disclosure condition compared to baseline, showing that listeners' explicit biases changed after listening to a self-disclosure that the speaker stutters. Results also indicated listeners exhibited a more negative implicit bias, based on computer mouse trajectories, when rating the PWS relative to the "persons who do not stutter" talker, but this negative implicit bias did seem to reduce over time after the disclosure was made. Conclusions These findings indicate that, even though explicit and implicit biases were evident when listeners heard stuttering, both explicit and implicit biases seemed to extinguish over time after a self-disclosure. Although the bias was not completely extinguished, these results provide promising evidence toward developing methods to reduce negative beliefs and reactions toward PWS.

Acoustic correlates of female confidence: A production and comprehension study.

In the current study, an interactive approach is used to explore possible contributors to the misattributions listeners make about female talker expression of confidence. To do this, the expression and identification of confidence was evaluated through the evaluation of talker- (e.g., talker knowledge and affective acoustic modulation) and listener-specific factors (e.g., interaction between talker acoustic cues and listener knowledge). Talker and listener contexts were manipulated by implementing a social constraint for talkers and withholding information from listeners. Results indicated that listeners were sensitive to acoustic information produced by the female talkers in this study. However, when world knowledge and acoustics competed, judgments of talker confidence by listeners were less accurate. In fact, acoustic cues to female talker confidence were more accurately used by listeners as a cue to perceived confidence when relevant world knowledge was missing. By targeting speech dynamics between female talkers and both female and male listeners, the current study provides a better understanding of how confidence is realized acoustically and, perhaps more importantly, how those cues may be interpreted/misinterpreted by listeners.

The Effects of Emotion Suppression During Language Planning and Production.

Purpose: Emotion regulation and language planning occur in parallel during interactive communication, but their processes are often studied separately. It has been suggested that emotion suppression and more complex language production both recruit cognitive resources. However, it is currently less clear how the language planning and production system is impacted when required to emotionally suppress outward displays of affect (i.e., expressive suppression). The purpose of the current study was to evaluate the interactive effects of emotion regulation and language production processes. Method: Through discourse analysis of a corpus of interactive dialogue, we evaluated the production of interjections (i.e., also termed "filled pauses," a type of speech disfluency) when participants regulated outward displays of emotion and when language was lexically complex (i.e., via lexical diversity). One participant (the sender) was assigned to either express or suppress affective displays during the interaction. The other person (the receiver) was given no special instructions before the interaction. The interactions were transcribed, and their linguistic content (i.e., lexical diversity, lexical alignment, and interjections) was analyzed. Results: Results indicated that participants actively suppressing outward displays of affect produced more interjections and that participants asked to emotionally regulate, both expressors and suppressors, were more disfluent when producing lexically diverse statements (2 cognitively demanding tasks). Conclusions: The current research provides support that, when suppressing emotion, one might be more disfluent when speaking. However, also when engaged in 2 simultaneous, demanding tasks of having to either upregulate or downregulate emotions and utter lexically diverse statements, the combined cognitive load may impede fluency in language production. More specifically, in the context of language planning and production, emotion suppression may pilfer resources away from the language planning and production system, leading to higher rates of disfluent speech. This finding is of particular importance because understanding the interactive effects of emotion and language production may be impactful to interventions for communication disorders.

Opposing roles for mammary epithelial-specific PPARγ signaling and activation during breast tumour progression.

BACKGROUND: Among women worldwide, breast cancer is the most commonly diagnosed cancer, and the second leading cause of cancer-related deaths. Improved understanding of breast tumourigenesis may facilitate the development of more effective therapies. Peroxisome proliferator-activated receptor (PPAR)γ is a transcription factor that regulates genes involved in insulin sensitivity and adipogenesis. Previously, we showed, using 7,12-dimethylbenz [a] anthracene (DMBA)-treated haploinsufficient PPARγ mice, that PPARγ suppresses breast tumour progression; however, the PPARγ expressing cell types and mechanisms involved remain to be clarified. Here, the role of PPARγ expression and activation in mammary epithelial cells (MG) with respect to DMBA-mediated breast tumourigenesis was investigated. METHODS: PPARγ MG knockout (PPARγ-MG KO) mice and their congenic, wild-type controls (PPARγ-WT) were treated once a week for six weeks by oral gavage with 1 mg DMBA dissolved in corn oil and maintained on a normal chow diet. At week 7, mice were randomly divided into those maintained on a normal chow diet (DMBA Only; PPARγ-WT: n = 25 and PPARγ-MG KO: n = 39) or those receiving a diet supplemented with the PPARγ ligand, rosiglitazone (ROSI, 4 mg/kg/day) (DMBA + ROSI; PPARγ-WT: n = 34 and PPARγ-MG KO: n = 17) for the duration of the 25-week study. RESULTS: Compared to DMBA Only-treated PPARγ-WTs, both breast tumour susceptibility and serum levels of proinflammatory and chemotactic cytokines, namely IL-4, eotaxin, GM-CSF, IFN-γ, and MIP-1α, were decreased among PPARγ-MG KOs. Cotreatment with ROSI significantly reduced breast tumour progression among PPARγ-WTs, correlating with increased BRCA1 and decreased VEGF and COX-2 protein expression levels in breast tumours; whereas, surprisingly DMBA + ROSI-treated PPARγ-MG KOs showed increased breast tumourigenesis, correlating with activation of COX-2. CONCLUSION: These novel data suggest MG-specific PPARγ expression and signaling is critical during breast tumourigenesis, and may serve as a strong candidate predictive biomarker for response of breast cancer patients to the use of therapeutic strategies that include PPARγ ligands.
